The interstellar object known as 3I/ATLAS, roughly the size of Manhattan, has recently demonstrated an unexpected ...

Interstellar object 3I/ATLAS is showing signs of "non-gravitational acceleration" as it reached its perihelion.

There are various methods to measure acceleration due to gravity. At Higher level all rely on one of the equations of motion. The measurements required will depend on the equation used. Watch this ...

The MICROSCOPE mission tested the weak equivalence principle with free-falling objects in a satellite. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

All objects in the absence of air resistance (friction) fall at the same rate regardless of their mass. Due to gravity the speed of an object dropped from rest from a height will increase at the rate ...

Even in some of the most extreme areas in the universe, Albert Einstein’s theory of general relativity seems to hold up. A test of a key tenet of general relativity using three stars has shown that ...

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...
